The ancient Maya civilization thrived in Central America for thousands of years. Skilled architects and engineers, the Maya constructed magnificent stone pyramids and temples without modern tools or machinery. They developed an advanced writing system using hieroglyphs, which were symbols representing words and sounds. Maya astronomers tracked the movements of planets and stars to create precise calendars. Farmers grew corn, beans, and squash using sophisticated irrigation systems. Today, descendants of the Maya still live in several Central American countries, keeping many traditional customs.
